I am currently in the process of opening up my own gym. I am shooting for a future opening day of about a year. I would like it to be less because I am really excited about this but I do not want to rush anything, I want to make sure I have all my ducks in the right water. How long ideally does it usually take a person to open up a gym? And what type of critical mistakes do gym owners make when trying to start up a gym?
